Bing’s middle name is a tribute to Kate’s mother Goldie Hawn (Kate’s older son Ryder’s middle name is Russell after Goldie’s boyfriend Kurt Russell), but what does his first name mean?

According to BabyNamesBase.com, Bingham is German for hollow. Hollow is also a town in England. However, Matthew explained his own reasoning for naming his boy Bing, writing: “For those wondering, Bingham is my mum’s maiden name and Bing Russell was Kurt [Russell]’s dad. Family connections all round!”

Following his baby name announcement, the rocker dad also tweeted:

“Mum and baby are strong and healthy. Mum was a warrior, Bing popped out after 4.5 hours of intense pushing!”
